“…전이계수는 농산물의 중금속 생물학적 이용도의 차이 를 확인하는데 이용되며, 실제적으로 토양에서 중금속 이동의 측정 지표로 사용된다. Lee(2012) 등은 토양 내 중금속이 농산물로 흡수되는 정 도는 토양의 특성에 따라 다르지만 작물의 중금속 흡수에 가 장 큰 영향을 미치는 인자는 토양 중 중금속 함량이며, 토양 중 중금속 함량이 증가함으로써 작물 내 중금속 함량이 증가 함을 확인하였다. 토양에서 농산물로의 중금속의 전이계수는 토양 특성, 식물체 부위, 그리고 농산물 종류에 따라 다양하 며, 카드뮴과 아연은 1∼10, 구리와 납은 0.01∼0.1로 산출되 었다 (Klocke et al, 1984).…”

“…It appeared that 0.01 M Ca(NO3)2 extraction was a better option for the determination of bioavailable metal(loid)s in soils. Lee et al (2012) reported various patterns of crop uptake and transformation of heavy metal(loid)s with different crop species, varieties, parts, growing seasons, plowing, and irrigation methods.

The Codex Committee of Contaminants in Food (CCCF) has been discussing a new standard for arsenic (As) in rice since 2010 and a code of practice for the prevention and reduction of As contamination in rice since 2013. Therefore, our current studies focus on setting a maximum level of As in rice and paddy soil by considering bioavailability in the remediation of As contaminated soils. This study aimed to select an appropriate single chemical extractant for evaluating the mobility of As in paddy soil and the bioavailability of As to rice. Nine different extractants, such as deionized water, 0.01 M Ca(NO 3 ) 2 Woo-Ri Go, Seon-Hee Jeong, Anitha Kunhikrishnan, Gyeong-Jin Kim, Ji-Hyock Yoo, Namjun Cho, Kwon-Rae Kim, Kye-Hoon Kim, and Won-Il Kim 465 IntroductionThe Ministry of Environment established the criteria of soil contamination for heavy metal(loid)s in the agricultural fields designated by the Soil Environment Conservation Law in 1996 (MOE, 1996). The Ministry of Food and Drug Safety also established the criteria of 0.2 mg/kg for cadmium (Cd) in polished rice in Korea (KFDA, 2000). Recently, our regulations for agricultural environment including soil, irrigation water, agricultural materials (fertilizer and compost etc.), and agricultural products are being gradually reinforced (KFDA, 2011;MOE, 2010a). The CCCF (Codex Committee of Contaminants in Foods) have been under discussion on the maximum levels for arsenic (As) in polished rice since 2010 (FAO/WHO, 2014).In Korea, the standard method of analyzing heavy metal(loid)s contamination in soils is by aqua regia digestion (MOE, 2010b). This method is acceptable to evaluate the environmental burden of pollutants to the soil and to decide the proper environmental management and human safety. However, this method is not useful for assessing the metal bioavailability to crops. In order to minimize the risk of heavy metal(loid)s to the agricultural environment, crops, livestock, and humans exposed during the agricultural activities, considering bioavailability for the remediation of heavy metal(loid)s is necessary for agro-food safety (Naidu et al., 2003;Heemsbergen et al., 2009;Kim et al., 2009;Salazar et al., 2012;Bolan et al., 2014). Even though the development of analytical methods for measuring the bioavailability of heavy metal(loid)s in agricultural soils was rare in Korea, various assessment techniques were already developed worldwide. Bioavailability of metal(loid)s in agricultural soils was determined mainly by the concentration of metal(loid)s, the species and fractions of a specific metal(loid), and the physico-chemical properties of soils (Ruby et al., 1993;Geebelen et al., 2002;Kim et al., 2012a). Various single and stepwise sequential extraction methods were suggested to estimate the bioavailability of heavy metal(loid)s in agricultural soils. The Soil Environment Conservation Law recommended the use of 0.1 M HCl for cadmium (Cd), lead (Pb), copper (Cu), chromium (Cr), nickel (Ni), and zinc (Zn) and 1.0 M HCl for As to evaluate their bioavailability ...

Environmental toxicity due to cadmium (Cd) pollution in croplands causes critical problems worldwide. Rice (Oryza sativa L.) is an important crop in Asia, including South Korea, and numerous studies have evaluated the relationship between Cd and antioxidants to alleviate Cd uptake from the soil into plants. However, information about the relationship between phosphorus (P) and antioxidants in rice seedlings is still limited with regard to Cd phytotoxicity. We therefore investigated the physiological responses of rice (Oryza sativa L. cv 'Dongjin') seedlings to Cd toxicity and the effect of P application on reactive oxygen species (ROS) and antioxidant changes. The exposure of rice seedlings to 30 µM Cd inhibited plant growth; increased the contents of superoxide, hydrogen peroxide, and malondialdehyde; and induced Cd uptake by the roots and leaves. Application of P to Cd-exposed seedlings decreased Cd-induced oxidative stress by enhancing the capacity of ascorbate (AsA) production and ROS-scavenging, and decreased Cd transfer from the roots to the leaves. These results suggest that P application alleviated Cd-induced growth inhibition and oxidative damage by restricting Cd translocation from the roots to the leaves and maintaining sufficient levels of AsA.Keywords: Antioxidant, Cadmium, Phosphorus, Reactive oxygen species (ROS), Rice ) in roots (A, C) and leaves (B, D) of rice plants grown in the 30 µM Cd-treated hydroponics with or without 6 mM phosphorus (P) application at the four-leaf stage after 14 days.Ⓒ The Korean Society of Soil Science and Fertilizer.

Science and Fertilizer Vol. 50, No. 4, 2017 Introduction 세계적인 산업화 및 도시화는 농경지, 농업용수 그리고 생활용수 등의 오염수준을 급속히 증가시키고 있다 (Galiulin et al., 2001;Kirkham, 2006). 카드뮴 오염은 환경적으로 부정적인 영향을 끼칠 뿐만 아니라 먹이사슬의 최 정상에 위치한 인간의 건강을 위협하는 치명적인 위해요소로 간주되고 있다 (Jan et al., 2015;Nagajyoti et al., 2010). • Korean Journal of Soil카드뮴은 전반적인 식물생장에 부정적으로 작용하며 세포분열을 방해하여 뿌리의 신장을 억제할 뿐만 아니라 보조인 자로 필수금속이온 (Cu, Zn, Mn, Fe 등)을 포함한 단백질들의 금속이온을 치환함으로써 펜톤반응 (fenton reaction)활성산소종 (reactive oxygen species, ROS)을 발생시켜 세포 내에서 지질과산화작용을 야기함으로써 세포막을 파괴 하고 최종적으로 세포를 사멸시킨다 (Barceló et al., 1988;Jung et al., 2015Jung et al., , 2016Lagriffoul et al., 1998;. 특히 카드뮴에 의해 발생된 산화적 스트레스는 활성산소종의 세포 내 축 적으로 인하여 탄수화물, 단백질, 지질 및 핵산의 생합성에 부정적인 영향을 미치고 산화 ․ 환원 항상성을 교란하여 정 상적인 생체 기능을 저해한다 (Gayomba et al., 2013;Singh and Agrawal, 2010;Singh et al., 2006, Xu et al., 2014.
